4 designs for Philips Luxeon Rebel LEDs

4 Designs for Philips Luxeon Rebel High Power LED's

 

Red - Original Sparkfun Design

Orange Round - My Design using Standard footprint produced by Ragworm UK

Purple - My design using standard footprint produced by OSH Park

Orange Hex - Original Design but with thicker copper and wider vias for better heat transfer. Produced by Ragworm UK.

 

I have tested all 4 in identical settings and found the Round designs to be better at getting the heat away from the LED and spreading it to cool passivly.

 

The original Hex design works well with a small RAM IC heatsink attached and some active cooling (a small fan) due to the cutouts that allow a through draft to add extra cooling)

 

All designs work well, The Ragworm boards use slightly thicker copper which seems to help shift the heat and keep the LED stable.
